Answer:

$20.63 if you tip on the pre-tax amount

Step-by-step explanation:

You pay $12.99 for the pizza, plus the 8% tax on the pizza, plus the 20% tip of the cost of the pizza, so if you tip on the pre-tax amount, you pay

$12.99(0.08) = $1.04 in sales tax

$12.99(0.2)   =  $2.60 for the tip

and $4 delivery charge,

so you pay a total of

$12.99 + $1.04 + $2.60 + $4 = $20.63

Marco wants to buy a new smartphone that costs $495, with some additional accessories. He has already saved $75. Write and solve
antoniya [11.8K]

Marco needs to save a minimum of $420 more to buy a smartphone.

<u>Explanation:</u>

Cost of a smartphone = $495

Savings = $75

Least amount of money, m that needs to be saved = ?

Additional savings, m = Total - initial savings

                              m = $495 - $75

                              m = $420

The inequality equation would be 75 + m ≥ 495

Therefore, Marco needs to save a minimum of $420 more to buy a smartphone.
